WATCH-HAND REMOVER.

SPECIFICATION forming part of Letters Patent N 0. 647,832, dated April 17, 1900.

Application filed February 16, 1900. Serial No. 5,425. (No model.)

To aZZ whom it may concern:

Be it known thatI, CARL G. HAR STRClM, a citizen of the United States, and a resident of Peekskill, in the county of VVestchester and State of New York, have invented a certain new and useful Watch-Hand Remover, of which the following is a specification.

Hy invention relates to tools used by jewelers, watch-repairers, and others for removside view of the same.

ing the hands from watches, and has for its object a device that surely and quickly performs the operation without danger of injury to either the hands or other parts of the watch and that requires only the fingers of onehand for its manipulation. These objects are attained by the means set forth in this specification and the accompanying drawings, which form a part thereof.

Referring to the drawings, in which like letters and digits refer to similar parts throughout the several views, Figure I is an edge view of the tool held vertically. Fig. II is a Fig. III illustrates the first movement of the tool when being applied to use. Fig. IV shows a section of the tool, in enlarged form, during the operation of hand-removing. Fig. V is a sectional view of the operating parts of the tool. Fig. VI is a bottom View of Fig. IV, and Fig. VII shows the lower end of the opening rod or spindle. Fig. II illustrates the tool or instrument in actual size and the normal positions of the several parts when not in use.

For manipulation the tool is'held by the handle a between the thumb, the middle, and third fingers, the index-finger being used to operate the opening-rod e e, which passes freely through the handle and projects beyond the end of the handle, as shown.

The handle is preferably screwed into a socket j in the hub c of the metallic piece, composed integrally of the parts 0 b 01, Figs. III and IV. The side extensions 12 are slotted, as indicated at 19, Fig. I, to receive the bars ff, these bars moving freely on pivots 1 1, Figs. III and IV. To the ends of the bars f f shorter bars M1," 7; are pivoted at 2 2, Figs. III, IV, and V. These shorter bars are in pairs, as will be seen by reference to Figs. I, V, and VI, the bars upon one side being indicated by 112' and upon the reverse side by 11 t". The free ends. of these bars are curved clusive.

on their outer faces, as at m m, Fig. IV, and concaved on their inner edges, as at n n, to

facilitate reaching under objects, as shown in Figs. IV and V. The six bars thus joined together would hang from the handle if it were suspended vertically, as shown in Fig. III.

The rod e e, that passes through the handie, is slotted at one end, as at h, Fig. VII, and has a rivet-hole 4 at right angles to the slot. This slotted end of the rod passes below the handle between the bars just described, as in Fig. III. A Levers Z 1 (shown entire in Fig. V by the cutting away of the bars 2' t') are of thin'steel and made to connect the free ends of the bars t 2' z" z" and the slotted end of-t-he rod 6, as in Figs. II to V, i11- When so connected and held vertically, as in Fig. III, the positions of the various parts would be as thereshown; but if the handle should be turned upper end'down then the parts would fall to the position shown in Fig. II and theextreme points of the bars 11 i would have no stability as to their distance from the handle. While the tool could be used in this form, its manipulation would be awkward.

To give the points stability and for other reasons to be explained, means are employed that are shown in Fig. V. The slotted end of the rode e is also bored to a suitable depth to receive a special spring 8 and a hardened steel plunger 0. The leaves Z are made in segmental form, the curved faces receiving the thrust of the springs through the plunger 0, as is clearly shown.

It will be observed by reference to Fig. V that the pressure of the plunger 0 is exerted upon the levers on each side of their pivot 4, and so long as the parts are free to move the extreme ends of the levers Z will be drawn together until the faces in contact with the plunger form a horizontal line under the plunger or until the meeting of the points of the levers t' with each other or with some object between them.

In the manipulation of this tool the handle is held as before described and pressure is applied to the rod 6 e, which I have called the opening-rod. Pressure on the rod puts pressure on the pivot 4, that secures the levers Z l, and as this pivot is in a vertical plane between the pivots 3 3 the points of the bars 2 V v n I 647,832

- handle a the bars f f are spreadapart, as in M are forced apart, as in Figs. III and V. In that position the points of the bars are, placed in juxtaposition with the object to he lifted, as on each side of watch-hands, as in Fig. V, t t indicating the hands, and r the arbor, to which they are attached. The pressure that has thus opened the points of the tool has, through the levers Z Z, Fig. V, put a tension upon the spring .9. As soon as the finger is removed from the rod e e the tension of the spring actingupon the levers ZZ forces the points of the tool close upon the object .to be operated upon. Then by pressing upon the Fig. IV, causing. the bars 1 'Z 2" z" to act as levers under the removable object, their curved ends m m, serving as 'fulcrums and their points as thesho'rt ends of the levers. It is obvious that the pressureis strong, and since 'it is applied on each side of the arbor holding the watch-hands it must be effective. Fig. VI further illustrates somefeatures of the construction ofthe tool. The levers Z Z over- .lap each other where they. join in the slot in the end of the rod ,6 e, and consequently do not lie in the same plane, as shown in this *figure. As compensation for this and to avoid distortion of the lever-bars, washers w w are ;pl aced'on reverse sides of the two levers Z Z,

as indicated;

'1 Having described my invention, what I claim, and desire to secure by LettersfPatent ofithe United States, is-- 1 A tool for removingthe hands of watches comprising the following elementszfla, handle ved with levers Z, Z, the double lever-bars 1', i,
